Question

In the figure below, $W_{AB}$ and $W_{CD}$ are work done during process $AB$ and $CD$. Which one of the following options is correct?

• A. $W_{CD}>W_{AB}$
• B. $W_{AB}>W_{CD}$
• C. $W_{AB}=W_{CD}=0$
• D. $W_{AB}=W_{CD}\ne 0$

Answer 1

The correct option is C $W_{AB}=W_{CD}=0$

From the figure, $AB$ and $CD$ are isochoric process, work done during an isochoric process $=0$
$\therefore W_{AB}=W_{CD}=0$
